Prosthetic Aortic Valves: Challenges and Solutions

Frontiers in Cardiovascular Medicine, 2018
Aortic Valve Disease (AVD) is the most common Valvular Heart Disease (VHD), affecting millions of people worldwide. Severe AVD is treated in most cases with prosthetic aortic valve replacement, which involves the substitution of the native aortic valve ...

Early surgical aortic bioprosthesis failure caused by cusp tear: A word of caution

Clinical Case Reports, 2020
Cusp tear is an increasingly described mode of failure of the Trifecta aortic bioprosthesis. Acute aortic regurgitation after implantation of a Trifecta in absence of endocarditis should suggest a cusp tear and be promptly treated with redo surgery.

Superiority of the Rockwood Clinical Frailty Scale for Assessing Long‐Term Outcome in Patients Undergoing Transcatheter Aortic Valve Implantation

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Background Frailty is associated with poorer short‐term outcomes after transcatheter aortic valve implantation (TAVI), and national guidelines recommend an assessment of frailty as part of the decision‐making process. However, multiple frailty indices are currently used in clinical practice, and it is unclear which has the best discrimination ...

Aortic Dissection With Pseudoaneurysm Formation Masquerading as Pulmonary Embolism After Transcatheter Aortic Valve Replacement

Catheterization and Cardiovascular Interventions, Volume 106, Issue 5, Page 2969-2974, November 1, 2025.
ABSTRACT Transcatheter aortic valve replacement (TAVR) is a commonly performed procedure for the treatment of severe aortic stenosis. While it is generally considered a low‐risk procedure, one of the rare potentially life‐threatening complications includes aortic dissection.

Prognostic value of longitudinal strain relative apical sparing in severe aortic stenosis patients undergoing TAVR

ESC Heart Failure, Volume 12, Issue 5, Page 3537-3551, October 2025.
Abstract Aims This study evaluated the prognostic value of the relative apical sparing pattern (RASP) of longitudinal strain (LS) in patients with severe aortic stenosis (AS) undergoing transcatheter aortic valve replacement (TAVR) and investigated whether its combination with pre‐procedural biomarkers enhances risk stratification.
